摘　　要：结合微放电效应的产生机理,介绍了星载微波大功率组件的微放电防护设计,通过多种手段提高微波有源电路的微放电阈值电平。最终通过真空微放电试验,验证了微放电防护设计的有效性。在此基础上,给出了微波大功率组件的试验数据,该组件适用于集中式星载雷达固态发射机,输出峰值功率在500W以上,具有良好的真空环境适应性。Based on production mechanism of muhipactor effect, muhipactor-proofing design of satellite-borne microwave high power modules is introduced. Many measures are taken to improve muhipactor threshold of microwave active circuits. The validity of muhipactor-proofing design is proved by vacuum multipactor experiment finally. Based on it test data of microwave high power modules are offered. The module is applied in integrated solid-state transmitters on satellite-borne radar. Its output peak power is greater than 500W and it has good environmental adaptability in vacuum.
